Evaluating a test suite that contains redundant test cases is necessary to reduce the cost of testing. The redundant test cases exist when both of the two test cases are executed the same lines of code. This research evaluates the test suite by identifying redundant test cases. Exact match approach is...

Recently, there have been many studies on Multi-agent Reinforcement Learning (MARL) in which each autonomous agent obtains its own control rule by RL. Here, we hypothesize that different agents having individuality is more effective than uniform agents in terms of role differentiation in MARL. We have...

To develop a complex computer system such as a robot that can communicate smoothly with humans, it is necessary to equip the system with a function for both understanding human emotions and expressing emotional signals. From both perspectives, facial expression is a promising research area. In our research,...

A non-photorealistic rendering method has been proposed to generate cell-like images in which cell-like patterns are represented in photographic images. Cell-like patterns are automatically generated by the change of density of photographic images. However, cell-like patterns are irregularly arranged....

Micro-precision Glass Insulated Terminals (referred to as glass terminals) are the core components used in precision electronic equipment and are often used for electrical connections between modules. As a glass terminal, its quality has a great influence on the performance of precision electronic equipment....

Test suite reusability measurement is important to obtain the value of reusability as the degree of effectiveness of reused test suite. The measurement in this experiment considers not only the frequency of the successful test suite to examine different objects but also the code coverage as the criteria...

With the trend of Industry 4.0, the communication established by Ethernet is becoming more and more common in the Industrial Control System (ICS), and it brings not only pros but also cons like vulnerabilities from information technology. Furthermore, most devices in the ICS are not ready for cyberattacks,...

We develop the system to decide the efficient layout of assembly production line by using Genetic Algorithm (GA). We call the system as Decision System of Plural Production-lines-layout by GA (PPG). PPG decides the efficient layout of production line by using GA, work-flow-line acquired by Chameleon...

Fever is one of the most common concern to be taken care by parents which sometimes force them to bring their children to the hospital emergency for continuous following up especially at night when sleeping. Fever is defined when the rectal temperature reaches over 38.0°C (100.4°F). Temperatures measured...

Analysis of large data sets is increasingly important in business and scientific research. One of the challenges in such analysis stems from uncertainty in data, which can produce anomalous results. This paper proposes a method for detecting an anomaly in time series data using a Support Vector Machine...

In recent years, music therapy has been performed with the aim at recovering the cognitive function of elderly people. In the previously reported system, it was necessary to input the subjective evaluation of the user to determine the next recommended song. In this study, variations in fingertip skin...

In this research, we propose a Convolutional Network with sub-Networks (CNSN), i.e., a Convolutional Neural Network (CNN) or base-model that can be divided into sub-models on demand. The CNN architecture, entails that feature map shapes are varied throughout the model, therefore, the hidden layer within...

In recent years, dual-arm robots have attracted more and more attention due to their advantages such as strong cooperation ability and high flexibility. With the improvement of real-time requirement of dual-arm cooperation, the inverse kinematics solution of robot becomes a key problem to be solved urgently....

Camarin High School is one of the schools in the Philippines that is making an initiative in improving Science, Technology Engineering and Mathematics (STEM) education through robotics education. In this paper, the authors report the development of a robotics program for students in junior high school....

The main focus of the RoboCup competitions is the game of football (soccer), where the research goals concern cooperative multi-robot and multi-agent systems in dynamic environments. In RoboCup, self-localization techniques are crucial for robots to estimate their own position as well as the position...
